aqua-tools I&E provides rapid microbiological analysis solutions for monitoring the quality of water used in industrial processes.

For many industrial sectors (energy, chemistry, agro-food, automobile, metallurgy, paper production, etc.), water is a major strategic resource. Water is used for a wide range of processes (cleaning, disinfection, rinsing, cooling, heating, cutting, surface treatment, producing steam and vapor, etc.) and to generate a large number of finished products.

In response to European directives (particularly the CE framework directive of October 23, 2000), which requires users to manage the use of natural resources in a sustainable and responsible manner, the issues raised by using an industrial water cycle have therefore become an integral part of environmental progress and performance measures implemented at production sites. Minimizing consumption, reducing the generation of polluting waste products, ecological treatment of effluents, recycling residual water, using rain water, managing health risks associated with water…the strategies used tend towards using water in a circular manner, while preserving resources, health and the environment.

Water quality: an economic and ecological challenge

Preserving water quality therefore constitutes a fundamental concern. Recycled, treated or stored water has a reduced technical quality due to the development of a complex biological flora (including bacteria, protozoa, algae, etc.) that most often takes the form of biofilms or gelatinous aggregates.

This biological burden not only interferes with equipment function (blockage, reduced output or performance, increased corrosion and scaling), but also affects finished products (changes in texture, color, viscosity, activity, stability, etc.). Water that is not carefully managed in terms of the microbiological content inevitably leads to a variety of economic losses:

• Optimizing cleaning-disinfection of water circuits to minimize the dose of chemical biocidal agents needed, closely define the zone to be treated or evaluate the effectiveness of a disinfection procedure.

Other analysis kits:

• QG21I™ for analyzing dirty process water (containing suspended matter) and for technical evaluation of a new disinfection treatment using the Biomass Stress Index.

• DSA™ for analyzing the interior surfaces of equipment (vats, reservoirs, filters) and evaluating samples (from collection devices embedded in the network to facilitate evolution of the level of contamination with biofilms and their speed of formation).

Other applications

• Industrial cooling towers: managing the risk of Legionella contamination in water cooling networks for industrial processes in the energy sector (thermal and nuclear power centers), the chemistry sector, the agro-food sector, etc.

• Technical water production: quality management in producing water used in the industrial sector (deionized, distilled, reverse osmosis-filtered water, etc.).
